矿区固体废物堆存区有大量废物矿渣堆存,存在高势能的人造泥石流和溃坝危险源可能性较大.为避免危险,本文采用微动谱比法选取广西3个历史遗留固体废物堆存区开展物探勘测工作,并结合少量钻探进行反演参数校对,得到不同面波波速区域、不同面波波速的微动谱比法反演参数最佳选择.结果表明,该区的低面波波速区,横波表层速度优选较小值(通常小于200 m/s);中等面波波速区,横波表层速度选择偏中等值(250 m/s左右);高面波波速区,横波表层速度优选较高值(通常为300 m/s以上),主要针对覆盖层较薄,占比小,基岩较完整区域.
Application and research of microtremor horizontal-vertical spectral ratio combined with drilling proofreading in historical solid waste storage area
There is a large amount of waste slag in the solid waste storage area,which causes a high potential energy of artificial debris flow and dam break hazard.In order to avoid danger,this paper chooses the micro-tremor spectral ratio method to carry out geophysical prospecting work and combines a small amount of drill-ing to verify the inversion parameters.The different surface wave velocity regions and different surface wave velocity and the best choice of inversion parameters of microtremor spectral ratio method are obtained in 3 solid waste storage area of Guangxi.The results show that in the area of low surface wave velocity,the pre-ferred value of shear wave surface velocity is small(usually less than 200 m/s),in the medium surface wave velocity area,the shear wave surface velocity is selected as the middle equivalent(about 250 m/s),in the high surface wave velocity area,the shear wave surface velocity is preferably higher(usually more than 300 m/s),mainly for the area with thin overburden,small proportion and complete bedrock.
